Once you have had a glimpse of awareness or Presence, you know it firsthand. It is no longer just a concept in your mind.
Eckhart TollePick up any history book, and I suggest you begin with studying the 20th century, and you will find that a large part of the history of our species has all the characteristics we would normally associate with a nightmare or an insane hallucination.
Eckhart TolleWhatever you accept completely will take you to peace, including the acceptance that you cannot accept, that you are in resistance.
Eckhart TolleWhen you look upon another human being and feel great love toward them, or when you contemplate beauty in nature and something within you responds deeply to it, close your eyes for a moment and feel the essence of that love or that beauty within you, inseparable from who you are, your true nature. The outer form is a temporary reflection of what you are within, in your essence. That is why love and beauty can never leave you, although all outer forms will.
